Sony PCG-GRV550 Power Adapter
The Sony PCG-GRV550 AC adapter has two main uses, to charge any and all batteries and to provide a source of power for the unit. When choosing a new adapter, choosing the Sony brand one will probably be the safest way to go. If you decide to buy an non-Sony adapter, please check on both the volts and amps outputs. A universal AC adapter is another possibility if yours is unavailable or backordered. Because Sony uses one power charger that powers multiple other machines, make sure you check the part number for the correct one.
Easy warnings of a poorly working power adapter
- The laptop does not run using just the AC power adapter
- Most Sony AC adapters will get warm to the touch when plugged in for any length of time
- Your Sony battery refuses to charge completely
